Stephen Wiltshire spoke his first words, ‘pencil’ and ‘paper’ at five years old. At the age of eight, the late British Prime Minister Edward Heath commissioned Wiltshire to draw the Salisbury Cathedral. At 11 years old Wiltshire drew a perfect, intensely detailed picture of the London cityscape after a single helicopter ride. Perhaps it is not surprising that Wiltshire was diagnosed with autism, when he was three years old.
